In my experience (Seattle) PS2s do quite well in the rain. Their grip falls off in cold weather in about the mid to high 20s in my experience. I've run P-Zeros, PS2s, etc. over the years and at this point will just stick to the best Michelin has (which at this point is the PSS which bests the PS2 in ALL categories and is significantly cheaper to boot!) My next set of tires will definitely be the PSS.
